I have CentOS 5 installed on my server. I'm in VPS server.
I have site where I have constant online ~150. First look on site looks OK. But when I go through links, sometimes I receive Out of memory PHP error. It looks like this
Fatal error: Out of memory (allocated 36962304) (tried to allocate 7680 bytes) in /home/armtimes/public_html/sites/all/modules/cck/modules/fieldgroup/fieldgroup.install on line 100
And always, not allocated memory is very small.
In average I have 30% CPU load, 25% RAM load. So I think here is not a physical memory problem.
I have no any error log in apache's log files. Nothing connected with this.
Past I have not met with this on my server and the problem appeared itself.
Besides this I'm receiving some server errors on mail.
cpsrvd failed @ Fri Sep 24 16:45:20 2010. A restart was attempted automagically. Service Check Method: [tcp connect] Failure Reason: Unable to connect to port 2086
Same for tailwatchd.
Support tried, and can't help me...
